The detection of Flat Spectrum Radio Quasars (FSRQs) in the Very High Energy (VHE, E>100
GeV) range is challenging, mainly because of their steep spectra in this energy band. Up to now,
only five FSRQs are known to be VHE γ-ray emitters, all of them have been detected by the
MAGIC telescopes, that discovered four of them in the VHE band. The observations in the VHE
band are crucial to understand their emission, specially to constrain the location of the emitting
region within the jet due to the absorption from their broad line region (BLR). Typically, FS-
RQs are detected during high flux states, enhancing the probability of detection with the current
instruments sensitivities. However, the last observation campaigns performed with the MAGIC
telescopes show emission during moderate states, thus challenging our understanding of the emis-
sion mechanisms in FSRQs. In this contribution, we give an overview and present the most recent
results of the three FSRQs 3C279, PKS1222+21 and PKS1510-089 in a multi-wavelength context
with special focus on MAGIC and Fermi-LAT simultaneous observations.
